Abstract

The invention, belonging to photoelectric material technology field, relates the new-type polyarylradicalacetylene luminescent material containing polyploidy sesquialter silicon hydride and preparing method. The invention uses fluorenes, thiophene, benzene, dehydrobenzene, carbazole and many kinds of polyploidy sesquialter silicon hydride as raw materials, and uses organic reaction to synthesize the polyarylradicalacetylene luminescent material containing polyploidy sesquialter silicon hydride which is organic / inorganic hybridization nano material. Due to the existence of polyploidy sesquialter silicon hydride, it is effective to stop the formation of aggregation, so the organic polymer material possesses the good organic polymer and spectroscopic stability. The organic / inorganic hybridization luminescent material possesses the high quantum efficiency and luminescent heat endurance. The material can be used to prepare organic light-emitting diode and other electron devices.

Description

technical field [0001] The invention belongs to the field of photoelectric new materials and technologies, and in particular relates to a polymer luminescent material containing polyhedral silsesquisilane and a preparation method thereof. technical background [0002] Organic conjugated polymers have been extensively studied due to their potential applications in electronic devices, such as polymer light-emitting diodes, polymer light-emitting cells, solar cells, organic field-effect transistors, and chemical biosensing. However, the inherent organic material properties of conjugated polymers make this material poor thermal stability, which seriously affects the service life of the device when it is applied to electronic devices; Low-energy acceptors such as base associates lead to impure luminescence color and low device efficiency. These disadvantages of conjugated polymer materials hinder the commercial application of conjugated polymer electronic devices. [0003] Rece...
